Some positive effects even have been seen on markers of the heart and blood vessels, as well, with a reduction of the level of fat in the blood and a decrease in cholesterol. Elderberry may even increase insulin secretion and improve blood sugar levels.

The American elderberry (Sambucus canadensis) is a deciduous shrub native to areas of the Midwest and Eastern North America. Fragrant white clusters of blossoms bloom each summer. In warmer areas, blossoms may appear throughout the year.

Raw berries should not be eaten as they can cause nausea and vomiting. And the bark, seeds, stems, leaves, and roots are inedible. They contain a cyanide-inducing glycoside, which in large quantities, is toxic.

Elderberries are safe when cooked. They may be consumed in pies, jams, juices, gummies, syrups, and wine. At this time, there is no standard dosage of elderberry to take when suffering from colds or flu but some suggest one tablespoon of syrup extract four times a day. It’s also unknown as to whether or not consuming elderberry products daily is beneficial.
